Calculating a Recidivism Probability Score for Compliance-Based Ignition Interlock Device Removal

1. A method for facilitating compliance-based ignition interlock device (IID) removal, the method comprising: receiving IID data from an IID installed in a vehicle of an offender; determining two or more risk factors in accordance with the IID data, including at least one factor of a low blood alcohol content (BAC) non-violations factor indicating a number of passed BAC tests in which the offender registered a non-zero BAC level that was below a threshold level; calculating a recidivism probability score based on a weighted combination of the two or more risk factors; and sending the recidivism probability score to a monitoring authority of the offender.

2. The method of claim 1, wherein the two or more risk factors include a date of IID installation factor that indicates how long the IID has been installed in the vehicle of the offender.

3. The method of claim 1, wherein the two or more risk factors include a date of last IID calibration factor that indicates when the IID was last calibrated.

4. The method of claim 1, wherein the two or more risk factors include a violation hour factor that indicates a time of day associated with one or more interlock violations registered by the IID.

5. The method of claim 1, wherein the two or more risk factors include an event values factor that indicates a factor description placeholder.

6. The method of claim 1, wherein the two or more risk factors include a blood alcohol content (BAC) violations factor that indicates a number of BAC violations during a reference period.

7. The method of claim 1, wherein the two or more risk factors include a service lockout factor that indicates a number of times the IID was locked during a reference period.

8. The method of claim 1, wherein the two or more risk factors include an early morning violation factor that indicates a number of failed blood alcohol content (BAC) tests occurring before a specific time of day.

9. The method of claim 1, wherein the two or more risk factors include a violation lockout factor that indicates a number of times the IID was locked due to an interlock violation during a reference period.

10. The method of claim 1, wherein the two or more risk factors include a circumvention factor that indicates a number of times the IID detected an attempted circumvention of the IID by the offender during a reference period.

11. The method of claim 1, wherein the two or more risk factors include a skipped test factor that indicates a number of times the offender skipped a blood alcohol content (BAC) test during a reference period.

12. A method for facilitating compliance-based ignition interlock device (IID) removal, the method comprising: receiving IID data from an IID installed in a vehicle of an offender; determining, from the IID data, at least one masked risk factor and at least one unmasked risk factor; calculating a recidivism probability score based on a combination of least one masked risk factor and at least one unmasked risk factor; and sending the recidivism probability score to a monitoring authority of the offender.

13. The method of claim 12, wherein the at least one masked risk factor includes a low blood alcohol content (BAC) non-violations factor indicating a number of passed BAC tests in which the offender registered a non-zero BAC level that was below a violation threshold level.

14. The method of claim 12, wherein the at least one unmasked risk factor includes a number of failed blood alcohol content (BAC) tests.

15. The method of claim 12, wherein the at least one masked risk factor is a factor that is determined using IID data that is not apparent based on feedback the offender receives from the IID.

16. The method of claim 12, wherein the at least one unmasked risk factor is a factor that is determined entirely based on IID data that is apparent based on feedback the offender receives from the IID.

17. A method for facilitating compliance-based ignition interlock device (IID) removal, the method comprising: receiving IID data from an IID installed in a vehicle of an offender; determining two or more risk factors in accordance with the IID data, the two or more risk factors including: a first factor of a low blood alcohol content (BAC) non-violations factor indicating a number of passed BAC tests in which the offender registered a non-zero BAC level that was below a violation threshold level; a second factor of an early morning violation factor that indicates at least one of a number of failed BAC tests or low BAC non-violations occurring before a specific time of day; calculating a recidivism probability score based on a combination of the two or more risk factors; and sending the recidivism probability score to a monitoring authority of the offender.

18. The method of claim 17, wherein the first factor is associated with a first weight and the second factor is associated with a second weight, and calculating the recidivism probability score is based on a weighted combinations of the first factor and the second factor.

19. The method of claim 17, wherein the two or more risk factors include a number of failed blood alcohol content (BAC) tests.
